Finding X and Y Intercepts in Linear Graphing

The video tutorial explains how to find the X and Y intercepts of a graph using the Cartesian coordinate system. It covers the definition and properties of intercepts, provides steps to find them from equations, and includes a practical example of calculating and plotting intercepts on a graph. The tutorial emphasizes that at each intercept, the other coordinate value is zero.

What is the starting point called in the Cartesian coordinate system?

• Origin

• Axis

• Intercept

• Coordinate

What is the x-intercept of a graph?

• The highest point on the graph

• The lowest point on the graph

• The point where the graph crosses the x-axis

• The point where the graph crosses the y-axis

If a point crosses the x-axis at x = -3, what is the y value?

• 3

• -3

• 0

• 1

What is the y-intercept of a graph?

• The point where the graph crosses the y-axis

• The point where the graph crosses the x-axis

• The highest point on the graph

• The lowest point on the graph

When finding the x-intercept, what value is y set to?

• 0

• 1

• z

• x

When finding the y-intercept, what value is x set to?

• 1

• y

• z

• 0

In the equation 2y = 6, what is the value of y?

• 2

• 4

• 3

• 1

What are the coordinates of the x-intercept if x = 1?

• (1, 1)

• (0, 0)

• (0, 1)

• (1, 0)

What are the coordinates of the y-intercept if y = 3?

• (0, 3)

• (3, 0)

• (3, 3)

• (0, 0)

What is the next step after plotting the intercept points on the graph?

• Label the points

• Ignore the points

• Connect the points

• Erase the points
